Micrel, Inc. MIC4423ZWM

The MIC4423ZWM is a dual inverting 3A-peak low-side MOSFET driver in a 16-pin wide SOIC package, designed for driving capacitive, resistive, or inductive loads requiring fast switching and high peak current. It operates from 4.5V to 18V supply voltage, features TTL-compatible inputs with a -5V input voltage tolerance, and delivers output voltage swings within 25mV of supply rails. The device offers matched rise and fall times of 25ns to 35ns into 1800pF loads, a typical delay time of 33ns to 38ns, and output impedance of 3.5Ω to 5Ω. It is latch-up protected against more than 500mA reverse current and withstands up to 5V noise spikes on the ground pin. The package has a thermal resistance of 120°C/W, and the device meets no specified industry standards beyond its electrical ratings. Input capacitance is 6pF, and supply current is 3.5mA with logic-high inputs and 350µA with logic-low inputs.
